title: [Diagnosis of a complete atrioventricular canal with infundibular pulmonary stenosis and left superior vena cava by 2-dimensional contrast echocardiography. Apropos of a surgically treated case].
abstract: The case of an eight year old child with complete atrioventricular canal, pulmonary infundibular stenosis and persistent left superior vena cava draining into the coronary sinus is reported. Two-dimensional echocardiography with injection of contrast in a left arm vein gave a precise and complete diagnosis of the malformations before catheterisation and angiography. The complete atrioventricular canal was demonstrated by apical four-chamber views. The pulmonary infundibular stenosis was visualised by a short axis subcostal view. Contrast echocardiography in the apical four-chamber view showed a right-to-left shunt at atrial level at the site of the ostium primum and a right-to-left shunt at ventricular level just below the hemivalve. The left superior vena cava was detected by a short axis suprasternal view which visualised its vertical trajectory as far as the coronary sinus. The lesions were confirmed at surgery, and a complete repair was performed.
